IRVIN O. ALLEN, OF FRANKLIN COUNTY, INDIANA.

The object of this invention, broadly? speaking, is to provide an exercising ,machine which will be'strong and durable in construction, neat and attractive in appearance, adapted to occupy a minimum amount of space, adapted to provide a maximum of efficiency with a minimum of -mechanical parts, and which can be manufactured and sold at'a comparatively low price. p

More specifically stated my object is to provide an exercising machine with which a plurality of exercising devices may be connected to provide various results and to afford the highest degree of efficiency; and

having means whereby the machine. will give any desired degree of resistance by reason of the resistance of atmospheric air, and having means whereby the degree of resistance may be instantly changed in order to meet various conditions and preferences of the operator thereof.

In-fine, my object is, to provide an exercising machine in which I employ normal atmospheric air as the element of resistance.

Other objects and particular advantages of the invention-will be brought out and will sug est themselves inthe course of the following description, and; that which is new will be correlated in the appended claims.

of the blades and by which theblades are mounted rotatably in position; l -i.

Similar indices denote like parts throughout the several views. In order that the construction, the operatlon, and the advantages of my invention may be more fully understood and appre c a'tedI will now takeup a detailed descriptlonthereof, in which I'will set forth the invention as fully and as comprehensively as'I may. I i

In the drawings letter A denotes the floor. line. Secured to the floor by a plurality of bolts 1 is the base 2. Adjustably securedin the base by the set-screw 3 is the vertical standard 4:. Secured around the upperend of the standard 'is the collar 5, which has a horizontal flange 6 integral therewith. V

i The gear-case comprises the two members 7 and 8 which are substantially identical: wlth each other, they being oppositely dis posed and secured together, as shown, by a plurality of bolts 9, there. being a gear-space formed therebetween in which are located the major gear 10 and the minor gear or pinion 11. The gear '10 is secured on the drive-shaft 12, the latter being revolubly mounted in the hub formed by the members 13 and 14:.which project laterally from the respective members 7 and v8. :The minor.

' pinion '11 will mesh withthe gear 10, as

shown in Fig. 4. The shaft 15 isrevolublyf mounted in the hub formed'by the members 16 and 1,7 which project, laterally from the respective members 7 and 8, substantially'as shown. V a The projecting portions of the shafts 12 and 15. extend in opposite directions with relation to each other, as shown in Fig. 2.

- The lower portions of the members 7 and 1 V. i

8 terminate in the respective flanges 18 and l9,'which together fit the flange 6, to which? they are secured by a plurality of bolts 20.

' Formed through the shaft 15 are :a plurality of small apertures z,".which are for' thepurpose hereinafter set forth.

.The, fan, or resistance element,zcompris'es ahub 21, including a plurality ofsocket" members 22 radiating therefrom, eachtwo' of which. areconnected by.a, web-section 23.5..

Extending 1. out: radially from the :socket members are the spokes. 24; filllrollnding each of the spokes is a helical spring 25, whose inner ends rest on its respective socketmember 22. Numeral 26 denotes a washer fitting thespoke 24' and resting on the spring 25. Numeral 27 denotes a clip, or block, having a central aperture 5 and end apertures e and 7", all of which apertures are parallel with each other, and as shown in Fig. 7. The spoke 24 fits in the aperture 7) whereby the clip is rotatably mounted on the spokev a shown in Fig. 6. A second washer 28 is placed onthe spoke 24 and it contacts withithe clip 27 as does also the washer 26. Numeral 29 denotes a cotter-pin which is inserted in an aperture formed through the spoke 24 and it is so located that before the pin 29 can be inserted the clip must be pressed inward against the resiliency of thespring 25, whereby the clip is frictionally clamped between the washers 26 and 28.

Each of the blades (four in this instance) is composedxof a single wire 30 which is bent into substantially the form shown in Figs. 1' and 2, the two ends thereof being brought parallel with .each other-and they are inserted through and are secured in the apertures e and f of the respective clip 27 Stretched over and secured to saidiwire, and extending across the space inclosed thereby, is the fabric 31, however other suit ablematerial may be employed ifdesired. LetterH denotes a cotter-pin which is inserted through the hub 21 and through one of the apertures a in the shaft 15 to prevent the fan from turning on the shaft 15.

From the above it will be apparent that the blades may be turned edgewise or flat, with reference to the direction of travel thereof, or to any degree of angle therebetween, as the clip 27 will rotate on the spoke 24 when the blade is turned, and that the spring 25 will retain the blade in any position to which it has been turned.v

On the projecting portion of the shaft 12 it is proposed to secure any one of a number of exercising devices,' as for instance the double pulley shown in Figs. 2 and 3, which comprises a core 32 which may be secured around and concentric of the shaft 12 byxmeans of a set-screw 2, or otherwise as desired. I Extending out from the core are the two endfianges 33 and 34 and the center flange 35, thereby forming two circular channels in each of which may be located one of the ropes or cords 36 and 37. The inner endsofboth of said ropes or cords are secured to the pulley, and said ropes or 'cords are adapted towind around the pulley in reverse directions with relation to each othernwhereby .asv one is being wound the otherwill be unwinding. Attached to the outer ends of theiropes or cords 36 and 37 are therespective'handles 38 and 39.. 7 Y As an example of another device tobe secured to-theishaft 12 is the crankflshown in Fig. 5. This crank comprises a bar 40, having at one end of the handle 41 which extends at right-angles thereto. Secured along the face of the bar40, parallel therewith and opposite to handle 41, is the bar 42 which has mounted thereon the sliding block 43, which is dove-tailed in connection with saidbar.

Extending out from the block 43 is the thimble 44 which is adapted to fit around the end of the shaft 12, to which it may be secured by the set-screw 45."

Models 0pcra'ncZz'.'The machine above described should be secured to a floor orthelike, as shown in Fig. 1, extending upward fr'om'the floor to any height desired as in-f dicated. Now by grasping the handlesSS and 39, for instance, the operator may alternately pull upon one handle and then-upon the other, and as the rope-or cord of'one unwinds the other will wind up, alternately.

Thes'emovements will cause the fan to revolve first in one direction and then in-the' other, the amount of resistance ofli'ered being determined by the angle to which the blades are set. Or if a movement be desired diiferent from that afforded by said handles then another exercising device may be substituted in place of the pulley, as for instancethe crank shown in Fig. 5. It is to be understood that any number of differentexercising devices may be substituted for the pulley or the crank, but of course all depending upon the resistance of the fan withrelation to the normal air.

I desire that it be understood that various changes may be made in the several details" of construction from that herein shown and described, without departing from the spirit of the invention and without sacrificing any of the advantagesth'ereof.

Having now fully shown and described my invention, what I claim and desire to'sa cure by Letters Patent of the 'UnitedStates,
